Add support to connect guest-console via serial
- support commandline parameter --serial, --serial-telnet-host and --serial-telnet-port - support serial options: 'socket', 'telnet' and 'none' - add support to find free ports for monitor-telnet and serial-telnet - replace nc with socat - change default port for monitor-telnet to 4440 - some bugfix
